16" Cragars, Off-Center Center Cap?

So I'm looking into buying some rims from someone on this board, but when I received the pictures, I noticed a few things.

First off, I went to Cragar's homepage and I could not find this style of rim (see picture below) in 16". Also, look at the center caps - one of them looks like it says Cragar extremely off center. The owner of the rims said they are all like that (even though one of the pictures didn't show them like that ). Is that normal?

The owner of the rims doesn't know much about them because they were on the car when he bought it. So I turn to you guys for help. Are these knock-offs?
